Limping unsuited connectors in LP as well as even calling a raise in LP (making plays against tight players on unscary flops) with the image of a solid TAG. I've found myself to be fairly successful (given the image) and opps are willing to fold their hand often to me. (This was primarily an experiment over about 7-8K hands, 2-tabling at NL100).
It's probably not considered EV+, but given decent post-flop play and image, could it be EV+?
